WALTER KIGER, OF ST. LOUIS, MISSOURI, ASSIGNOR OF ONE-HALF TO ALBERT O. OBTERMANN JR, NURSERY, MISSOURI.

ELECTRIC FURNACE FOB HEATING E'OLDERING GQYPPERS.

Application filed August 17, 1922. Serial No. 582,491.

To all whom it may concern:

Be it known that I, \VALTER H. KIGER, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented a certain. new and useful 1mprovement in Electric Furnaces for Heating Soldering Coppers, of which the following is a specification.

My invention relates to an electric furnace. for heating soldering coppers.

The object of my invention is to provide tubular heating elements into which a soldering iron, or copper can be placed forheating same without danger of burning the tinned point thereof.

A further object of the invention is to provide a heat chamber having an insulated base for supporting the heating elements within the heat chamber.

A further objectof the invention is to provide a support at one end of the insulated base for supporting the handle end of the soldering coppers while the copper-s are carried within the heating elements.

X further object of the invention is to provide the front wall of the heating chamber with openings for the passage of soldering coppers therethrough.

\Vith the above and other objects in view, the invention consists in the novel features of construction, arrangement and combina tion of parts hereinafter more fully de scribed and finally pointed out in the claims hereto appended.

Referring to the accompanying drawings forming a part of this specification, wherein like references indicate like parts throughout the several views:

Fig. 1, is a vertical sectional elevation taken on line 1-1 of Fig. 2.

Fig. 2. is a sectional view taken on line 2-2 of Fig. 1.

Fig. 3, is a wiring diagram of the electrical connections.

Referring to the drawings, the reference character 1 designates a base plate made from any suitable insulating material and supported at each corner by means of a suitable supporting leg 2. The reference character 3 indicates a suitable housing, or casing which is suitably supported upon and at one end of the insulator base 1. The housing 3 is provided with a removable back plate 4e and a removable front plate 5 having the openings 6 for the passage of soldering coppers A, as will be more fully understood hereinafter. The top of the housing or casing 3 is provided with a vent 7 The interior of the housing forms a heat chamher 8. 1'

Secured to the insulating base 1 and supported within the heating chamber Sare one or more electrical heating and copper supporting elements, each of which comprise a tubular, open-ended core 9 and the electric winding 10 constituting the heating circuit;

Two looped conductors 11 engage the ends of each coil core 9 and their lower ends 12 are removably fixed to the upper ends of a pair of conducting posts 13 by means of the fastening means 142 for supporting the coils within the heating chamber. The lower end of each conducting post, or strip 13 is bent to form a foot 15 which is held in fixed relation to and upon the insulating base 1 by means of a suitable binding-post 16. Theends of the coil winding 10 are fixed to the looped conductors, as at 17. It will thus be seen that the conducting strips serve a dual function in that they serve as the sup porting means for the heating elements and also serve to transmit the heating current as part of the electric circuit of the system.

Each heating coil is connected with a suitable source of current 18 by means of insulated wires 19 and 20 and the current to each coil is controlled by means of a switch 21.

The operation of the device will. be easily understood from the above description. The soldering coppers are inserted into the tubular heating elements, after passing through the openings 6 of the front housing plate 5. After the coppers have been positioned within their respective heating elements, the switches 21 are closed and the coppers are soon heated for use.

The lower ends of the binding posts 16 and the conductors leading therefrom are cove-red or protected by means of the coverplate 22.

The handles 23 of the soldering coppers A are supported by means of an inverted U-shaped supporting member 24 which is fixed to and supported by the insulating base 1.

From the foregoing description, it will be apparent that there is provided a simple structure which comprises as a unit, tubular heating elements for receiving soldering coppe-rs, a housing to provide a heat chamber for the heating elements, and a support for the handles of the soldering coppcrs conveniently arranged in combination with the insulating leg supported base plate.

The many advantages of the herein described invention will readily suggest themselves to those skilled in the art to which it appertains.

I do not desire to be understood as limiting myself-to the exact details of construction and arrangement of parts as herein described and illustrated, as it is manifest that variations and modifications may be made without departing from the spirit and scope of my invention and the terms of the following claims, hence I wish it to be understood that I reserve the right to make any such changes, or modifications as may fairly fall within the scope of the appended claims when fairly construed.

\Vhat I claim is:

1. In an electric soldering furnace structure, a leg supported insulator plate, a housing removably supported at one end of said plate, said housing having a heat vent in its upper wall and a removable front plate having openings therein, a soldering iron handle support fixed to opposite ends of said plate, tubular insulator heating members disposed within said housing, support ing members fixed to said plate below said insulator heating members, a connection be tween said supporting members'and 03])0- site ends of said insulator heating mem ers for supporting said members above said supporting members, a heating coil wound about said tubular insulator heating members having connection at opposite ends with the connections between the insulator heating members and the supporting members, circuits formed through the medium of said supporting members and said heating coils and a switch for each circuit.

2. In an electric. heater structure for soldering irons, a leg supported insulator base, a pair of opposed metallic supports, terminal means passing through the insulator base for fixing the lower ends of said supports to said base, a tubular insulator heating member, a metallic connection between the upper end of each supportand the heating member to support said heating member above said supports, a housing removably mounted upon one end of said in sulator base enclosing said supports, heating member and its connections, said housing having a hot air vent in its upper wall and provided with an opening in its front wall to permit the passage of a soldering iron therethrough to be supported within the heating member, a support fixed to the opposite end of the insulator base for supporting the handle of a soldering iron, a heating coil wound around said heating member having its ends connected to the connections between the supports and the heating member, a circuit formed through the medium of said supports and said heating coil and a switch for said circuit.

In testimony whereof, I have hereunto signed my name to the specification.
